'Nightline' accompanied Taylor Swift on the sweltering August photo shoot for her third Glamour cover. If it's any indication of her personality, the 'Begin Again' singer was on time and entourage-free when she arrived. She was chatty and friendly with her interviewers as she changed into outfit after outfit and demonstrated makeup look after makeup look for the shoot. During the sit down, Swift expressly avoided talk about boyfriend Conor Kennedy and admitted that she's a big worrier -- she worries about everything from the past to what school she will send her kids to.

That's what makes us love Swift -- she worries about the future of kids not yet born. That's some pretty deep thinking there. In her sit-down, the Kennedy conversation inevitably came up, but the 22-year-old 'Red' starlet. cut it off at the pass. "I don't talk about my personal life in that great detail," she said when asked about dating Conor. "I write about it in my songs. In an interview, it's not as much what I do."

Case closed.

Swift also spoke about her worry wart nature, saying, "I worry about everything. The future, the past, the present. Where is this all going? What am I going to feel like in 20 years? What about 28 years? Where am I going to send my kids to school?"

For someone who has the world eating out of the palm of her hand, Swift sure worries a lot. Even so, it shows her propensity for forethought.

Her now-infamous "awards face" came up, too. You know, that "Aw shucks, I can't believe I won" reaction, where her mouth drops to the floor and she holds her cheeks in her hands? The face has made her the butt of more than a few jokes at country events and on 'Saturday Night Live,' but Swift pointed out that she is genuinely surprised anytime she wins, and she will never be blaze about taking home a trophy.

"People make so much fun of me for that," she said. "If you win an award, isn't that crazy? How can you be like, 'Oh, another Grammy? I'm going to get that now.'"
